Roy, I actually bought the Dynacorn 69 Camaro Convert. body and modified it to 69 FB convert. I changed out the dash and tail panel for my old original ones, closed the gill slits and changed the rear qtr markers. That said, the fit of the panels took some extra work, the doors and the trunk had to be adj. cut, and in trunk lids case, metal added to get correct margins and fit. I had original 69 fenders and they had to be cut to fit the door margins. The Body shop, MoMuscle Cars has since purchased a new Camaro body and fenders from Dynacorn for another customer, had a bunch of fitting issues.
A shop/parts supplier in New Hampshire, "Muscle Car Metal" deals with building new FGF bodies, and uses Goodmark Products. the Owners name is Tony, he is a straight shooter and will get your parts for you if they are available. He is a dealer for both Goodmark and Dynacorn. Do search for Muscle Car Metal (MCM), on Google, should come up ok, give him a call, he does return messages. If not, I have his sisters number somewhere, I can dig it up. My e-mail is: mtgriz70@earthlink.net.
